net.sf.ehcache.constructs.blocking.SelfPopulatingCache
A selfpopulating decorator for {@link Ehcache} that creates entries on demand.
Clients of the cache simply call it without needing knowledge of whether the entry exists in the cache.
The cache is designed to be refreshed. Refreshes operate on the backing cache, and do not degrade performance of {@link #get(java.io.Serializable)} calls.
Thread safety depends on the factory being used. The UpdatingCacheEntryFactory should be made thread safe. In addition users of returned values should not modify their contents. @author Greg Luck @version $Id: SelfPopulatingCache.java 744 2008-08-16 20:10:49Z gregluck $
